Hazardous UV levels hit major Vietnamese cities
The ultraviolet (UV) index in Hanoi, Ho Chi Minh City, and other southern localities is at a 'very high' level today, according to reports by the National Center for Hydro-meteorological Forecasting (NCHF).
This comes after the highest UV level in Ho Chi Minh City on October 5 was recorded at 8.1, while in Hanoi the UV level was at 7.7.
In other northern localities, including Hai Phong city and Ha Long City of Quang Ninh province, the UV index was at 6.5 and 7.8, respectively.
Meanwhile, central cities in the south-central province of Khanh Hoa, such as Hue, Da Nang, and Nha Trang City, saw the UV level reach 7.5, 5.8, and 7.0, respectively.
Typically, a UV index between 2.5 and 5.4 can be considered moderate, while the 5.5 to 7.4 range being high, whilst the 7.5 to 10.4 range is very high.
A UV reading at the very high level is capable of penetrating clouds and glass windows, while also causing sunburn after 25 minutes of exposure.
NCHF forecasts that the UV index in these cities will continue to remain high, with very high levels anticipated from October 6 to October 8.
Residents are therefore advised to remain indoors from 10:00 a.m. to 1:00 p.m.
Those who need to go out outside should protect themselves with jackets, gloves, hats, sunglasses, and sunscreen, as well as staying hydrated by drinking a sufficient amount of water and eating fruits rich in vitamin C.
